EP-ZQ80 Injection Blow Molding Machine

The 55 mm screw delivers a 466 g shot through a precision hot runner into the injection mould. The 800 KN injection clamp — among the highest in this weight class — holds the mould shut without deflection even at 12-cavity or 14-cavity tooling loads. Each preform exits the injection station with its neck finish, thread form, and body profile fully dimensioned. The high-precision angle divider fires the 120° index synchronously with mould opening — zero lag, zero positional drift.

The blow mould closes around the preforms with 120 KN clamping force. The hydraulic double system — standard on the ZQ80 — maintains stable blow-station clamping pressure independent of the injection-side hydraulic demand. Compressed air at 0.8–1.2 MPa expands each preform against the machined cavity wall. After the cooling dwell, the blow mould opens and the turntable indexes to Station 3.

Bottles are ejected from the cold rods by the 230 mm stripping mechanism and conveyed downstream. All three stations — inject, blow, strip — operate in parallel. The EP-ZQ80’s dual 18.5+18.5 KW motor layout balances injection and clamping loads across separate drive circuits, reducing thermal buildup during extended runs and sustaining the 4-second dry cycle across full shift production without thermal throttling.

At 800 KN, the EP-ZQ80 exceeds its weight class by 20–30% on injection clamping force. This extra rigidity means that high-viscosity HDPE and PP resins — which generate higher cavity pressure than LDPE or PS — can be run at maximum cavity count without flash. Mould maintenance intervals extend substantially because parting surfaces are never stressed beyond specification.

The ZQ80 is the first model in the EP-ZQ range where injection and clamping loads are distributed across separate motor-drive circuits. A single 37 KW motor handling both loads would experience peak current draw during the simultaneous injection and clamp-close event. The dual 18.5+18.5 KW layout separates these demands, reducing peak current, cutting heat generation, and allowing both motors to operate at higher efficiency on their respective load profiles.

The standard high-precision angle divider on the ZQ80 achieves simultaneous mould open/close and rotary table lift — the two actions that determine index time. By running these motions in parallel rather than in sequence, it delivers the 4-second dry cycle without requiring higher motor speed. The result is the same throughput benefit as a faster machine, but with lower mechanical stress and less wear on the rotary bearings over the machine’s service life.

The ZQ80’s 12 cavities at 100 ml make it the natural choice for daily-chemical producers running hand-wash, shampoo, body-wash, fabric conditioner, and household cleaning products at volumes of 1–3 million units per month. HDPE and PP are the standard resins. The dual-motor layout sustains output across 3-shift operations without thermal derating.

HDPE and PP tablet, capsule, and oral liquid bottles from 30 ml to 500 ml for GMP-regulated pharmaceutical producers. The ZQ80’s 800 KN injection clamp means neck-finish consistency is maintained even at 14-cavity (30 ml) tooling — a critical requirement for tamper-evident closure compatibility in regulated markets.

PS lactic-acid bacterial drink bottles (65–250 ml), drinking yoghurt containers, liquid condiment bottles, and cooking-oil dispensers. Running PS at 18 cavities (30 ml) or 14 cavities (60 ml), the ZQ80 covers mid-to-large food packaging volumes with the same zero-flash output quality as a pharmaceutical line.

PCTG and EVA luxury cosmetic bottles and personal-care dispensers for brands running volumes that exceed what the ZQ60 can cover in a single shift. The 800×400 mm platen on the ZQ80 accommodates more complex multi-cavity tooling layouts than the ZQ60’s 600×390 mm platen allows.

A Bangkok-area daily-chemical producer supplying a regional FMCG chain with 250 ml HDPE hand-wash bottles at 2 million units per month selected the EP-ZQ80 over competing machines after evaluating that its 800 KN injection clamp was the only configuration in this weight class that could run 12-cavity 100 ml tooling without flash on high-viscosity HDPE. The 4-second dry cycle, combined with 12 cavities, delivered the monthly volume target in 2.8 shifts — leaving capacity for additional SKUs.

A pharmaceutical packaging operation in Düsseldorf running HDPE tablet bottles (60 ml, 100 ml, 250 ml) for branded OTC clients needed a machine that could handle all three formats from a single platform without a full tooling rebuild. The EP-ZQ80 accommodates 14-cavity (60 ml), 12-cavity (100 ml), and 8-cavity (250 ml) tooling on the same 800×400 mm platen — all within the machine’s 800 KN injection clamp budget. Changeover between formats was achieved in one 6-hour maintenance window.

A Guangzhou dairy producer running 65 ml PS lactic-acid bacterial drink bottles at 3 million units per month selected the EP-ZQ80 for its 18-cavity (30 ml) and 14-cavity (60 ml) capacity. Running at 14-cavity 65 ml equivalent tooling, the machine covers the monthly target in 2.5 shifts. The production team noted that the dual-motor configuration eliminated the thermal shutdowns that had plagued their previous single-motor machine during peak summer ambient conditions.

A Riyadh cosmetics manufacturer producing EVA and PCTG luxury skincare bottles at 150 ml for the Gulf retail market needed consistent optical clarity and dimensional uniformity across 10-cavity tooling. The EP-ZQ80 delivered both — haze values consistently below 1.8% in PCTG and weight variation under ±0.6 g per cycle. The client’s quality manager stated that the ZQ80’s output “is indistinguishable from Italian-made containers at a fraction of the machine cost.”
